How many varieties of wheat with short stalks and big ears are there in the national trial?

The varieties of short-stalk, big-spike wheat approved by the state include Bainong 4199, Tianmin 198, Luomai 1, Xuke 168 and Jingdong 18.

1. Bainong 4199

This variety has wide adaptability to high yield and early maturity, good frost resistance, fast grain filling speed and good grain commercialization, and it has outstanding popularization performance in southern Henan, and is suitable for corn and wheat harvesting.

is a semi-winter mid-early maturing variety with a total growth period of 229-23 days. The seedlings are semi-prostrate, with short and wide leaves, dark green leaves and good cold resistance in winter; The ability of leaf separation is average, the rate of ear formation is high, and it gets up early in spring and jointing, polarization is fast and heading is early; The plant type is relatively compact, the flag leaf is small and uplifted, the plant height is 68.1-75. cm, the stem elasticity is weak, the lodging resistance is general, it is sensitive to the low temperature in spring, and there is a phenomenon of virtual tip.

2. Tianmin 198

Weak spring precocious variety, the whole growth period is 218 days. The seedlings are upright, with average growth, short and wide leaves, yellow-green leaves and average cold resistance in winter. Strong leaf splitting ability and high ear formation rate. In spring, the polarization speed is fast, the heading is early, and the resistance to late spring cold is average. In the later stage, the high temperature resistance is better, and the ripening ratio is better. The plant height is 7 cm, the stem is thick, and the lodging resistance is good. The plant type is loose, the flag leaf is wide and long, and it is upward, with delicate appearance, long lower panicle node, thick panicle layer, large and sparse panicle and even panicle.

3. Luomai No.1

The seedlings are upright and the leaves are light green. The plant type is compact, and the flag leaves are upward. The leaf splitting ability is average, and the ear forming rate is medium. The stem is stout and has good lodging resistance. The spike is rectangular, with long awn, white shell, red grains and strong horniness. Identification of disease resistance: moderately susceptible to powdery mildew, moderately resistant to scab and sheath blight, moderately resistant to powdery mildew, moderately resistant to scab and sheath blight.

4. Xuke168

is a semi-winter medium-late maturing variety with large spike type, with a total growth period of 225-234 days. The seedlings are semi-erect, with wide and long leaves, light green leaves and good cold resistance in winter; Moderate leaf splitting ability, early jointing in spring, rapid polarization, early heading, and average resistance to late spring cold in spring.

The plant type is loose, the flag leaf is long, it lifts upward, the lower ear node is short, the ear layer is thick, the plant height is 76-83 cm, and the lodging resistance is good; Spindle-shaped spike, short awn, white shell, white grain, uniform size, semi-horny, good plumpness and high black embryo rate; Good root activity, long leaf functional period, high temperature resistance in the later period and good yellowing when mature.

5, Jingdong 18

belong to winter wheat, with middle and early maturity, and the heading maturity is similar to that of Jing 411. The seedlings are semi-prostrate, the leaves are dark green, the leaf separation ability is moderate, the plant height is 75-8 cm, and the plants grow luxuriantly. The rate of ear formation is high, the ear is spindle-shaped, with long awn, white shell and white grain, and the grain quality is hard and full.

The yield factors are relatively coordinated. The average number of ears per mu in the regional test is 442,6, the number of grains per ear is 31.6, and the 1-grain weight is 41.9 grams. Good lodging resistance and moderate cold resistance; Identification of disease resistance: high resistance to stripe rust, leaf rust and powdery mildew.
